A 30 year old hand told me my tube rolling technique looked like I was mad at the metal
Was tacking up a shell last week at the shop when a retired boilermaker who was picking up some scrap stopped and told me I was rolling my tubes like I was mad at the metal, said the old timers would roll them slow and let the tool do the work. Tried it his way on the next pass and cut my time by about 20 minutes and the seal checked out first try on the hydro. Anybody else have an old timer correct their technique and end up wondering who taught them wrong in the first place?
I mean, cutting 20 minutes is nothing to sneeze at, but I'd pump the brakes on the whole "who taught me wrong" thing. Sometimes you just develop habits over the years, doesn't mean whoever trained you was clueless. The old guy's advice worked for you on that shell, sure, but every job and every tool rolls a little different, so what saves time one day might not the next. Take it with a grain of salt and just be glad the hydro passed.
